This invention relates to a transportation attachment for offset discs,harrows, and other farm equipment.

An object of this invention is to obviate the 5 costly loading andunloading of equipment on a trailer or truck.

Another object of the invention is the con,- struction of an attachmentof the class hereinafter specifically described which can not only l beused on the offset disc, but also on any piece of equipment which onewishes to move.

The attachment is particularly advantageous to city or private lotcleaning concerns as the mechanism can travel over streets, curbs andsidewalks without injury to same.

A still further object of the invention is the provision of manuallyoperated units near the corners of a frame, whereby a mechanism can bequickly adjusted for operation on a lot or field,

20 or, when desired, the mechanism can be adjusted to place the same inan inoperative position, whereby wheels are placed in position forconveying the mechanism over surfaces, without injury to such surfaces.

With the foregoing and other objects in View, the invention comprisescertain novel constructions, combinations and arrangements of parts aswill be hereinafter fully described, illustrated in the accompanyingdrawings, and more par- 30 ticularly pointed out in the appended claims.

Referring to the drawings by numerals, I designates a frame whichcomprises the front section 2 and the rear section 3. Each sectionincludes parallel longitudinally-extending beams 4 to which are securedparallel transverse beams 5. The sections of the frame are suitablyconnected together, as the connection is not a part of this invention,nor are the discs, since my transportation structure may be applied toframes of different farm equipment.

In the drawings I have preferably shown four sets of wheel-carryingcrank-axle units of similar construction, all attached to a frame,preferably near the corners of the sectional frame. Therefore, as thesecrank-axle units are duplicates it will only be necesary to specificallydescribe one. The crank-axle unit, near each corner of the frame I,comprises a pair of parallel substantially U-shape inverted suspensionbrackets 6. Each suspension bracket 6 includes a horizontal body portionl integral with parallel depending legs 8; each leg terminates at itslower end in an outwardly-extending horizontal foot 9. The feet 9 ofeach bracket 6 are preferably secured by bolts I0 to the samelongitudinally-extending beam 4.

A crank-axle is employed comprising a horizontal portion II integral atits outer end with an inclined vertical portion l2, and this portion I2terminates at its outer end in a spindle portion I3; to the spindleportion I3 is fixedly secured a spindle I4 upon which wheel I5 ismounted. All of the wheels I5 are preferably provided with pneumatictires. Integral with the central portion of the horizontal portion II isa handle I6. This handle I5 includes an inner portion I'I, a centralportion I8 and an outer portion I9 (Figs.

7 to 9). The portions Il and I9 are preferably formed in parallelplanes. The horizontal portion II of the crank-axle is placed under thehorizontal bodies 'I of suspension brackets 6, and U-shaped bolts areplaced around this portion of the axle, with the bolts extending throughbodies 'I, and nuts 2I are on said bolts 20, whereby the axle isrevolvably mounted upon brackets 6. Against the outer edge of eachbracket 6 and mounted on portion II of the crank-axle are lockingcollars 22; these collars are xedly secured to portion Il by anysuitable means, such as a set screw, not shown. These collars 22 keepthe crank-axle in correct position upon brackets 6, preventing anylateral movement or play. When the wheels are in engagement with thesurface over which the mechanism is to pass, the outer portion I9 of thehandle of the axle unit will be under the primary lock hook 23 (Fig. 7).When the wheels are raised to the inoperative position, as clearly shownin Fig. 3, with the discs in engagement with the ground, then thehandles are hooked under the comparatively long auxiliary lock hooks 24.

In Figures y11 and 12 I have shown a modification designed particularlyfor orchard work, so that the wheels and the portions of the axles whichstick up can be removed with very little effort, thus giving a disc thatcan be used for close work. In this embodiment the vertical inclinedportion I2a is made of two sections, and on the abutting ends of thesesections I place an annular clamp or sleeve 25 which has parallel lips2B. Fastening bolts 2l extend through these lips 26, with-nuts thereon,whereby the sleeve can be securely clamped upon the ends of the portionl2a. A spline or key 28 is in the abutting ends of the axle section aswell as in sleeve 25, preventing rotation of said sleeve on the axle. Bythis means the wheels can be quickly removed from the apparatus, andlikewise can be quickly replaced after removal.

In carrying out my invention it will, therefore, be seen that I havepreferably shown a frame provided with parallel longitudinally-extendingbeams upon which the suspension brackets are specically mounted forsupporting the crankaxles.

In operation when the crank-axle units are in the position shown inFigures 1 and 2, the wheels l5 will be in engagement with the surface,and the handles of the crank-axle units will be hooked under the primarylocking hooks 23. When the operator desires to p-lace the mechanism inposition for the harrows to operate, all he has to do is to slightlymove each handle to one side, to disengage it from hook 2S, or as hook23 is pivotally mounted on the frame at 23a the hook itself can be movedto easily release the handle, whereupon the operator can swing thehandle in a half circle, so as to bring it in engagement with theauxiliary locking hook 2Q, as clearly shown in Figure 8. Then the discswill be in position to operate.

It is also to be understood that the novel crank-axle units may beattached in like manner to frames of other equipment than a disc harrow.

While I have described the preferred embodiments of my invention andillustrated the same in the accompanying drawings, certain minor changesor alterations may appear to one skilled in the art to which thisinvention relates during the extensive manufacttue oi the same, and I,therefore, reserve the right to make such changes or alterations asshall fairly fall within the scope of the appended claims.
